-This function is marked as ``legacy'' in POSIX.  Better use @code{utime}
+The declaration of this function lacks @code{const} in the second argument

+On some platforms, this function mis-handles trailing slash:

+This function cannot set full timestamp resolution.  In particular,

+@code{utimensat(AT_FDCWD,file,times,0)}, or the gnulib module utimens,
 instead.

+On some platforms, @code{utimes (file, NULL)} fails to set the

+Extension: Gnulib provides a module @samp{utimens} that works around these
+problems and allows to set the time with nanosecond resolution (as far as
+supported by the file system).
